@q-bert Use the command "nmcli dev status" (for Network-Manager) or "networkctl" (for systemd-networkd) and make sure the NIC is not off / unmanaged.

Update: I reported this bug to OpenMediaVault and it was fixed in OpenMediaVault Version 6.8.0. https://github.com/openmediavault/openmediavault/commit/82c74b07fb7f57a6c55832f6e3aa17ba6b67b55d (Issue #1589: Fix a problem in the netplan.io configuration for ethernet network interfaces with non-permanent MAC addresses.) For stock Armbian with Network-Manager you still have to make sure that the Realtek RTL8125 2.5GbE NIC is correctly configured.

I have Armbian running on a NanoPi R6C 8GB with 32GB eMMC. I made a new Armbian image with the build framework that uses newest linux-u-boot-nanopi-r6s-legacy 23.8.0-trunk linux-dtb-legacy-rk35xx 23.8.0-trunk linux-image-legacy-rk35xx 23.8.0-trunk Booted from microSD this system has an idle power consumption of 0,92w. I can access both the eMMC and microSD storage. When i transfer this system from microSD to eMMC with "nand-sata-install" to boot & OS on eMMC and cold boot without the microSD, the idle power consumption increases to 1,21w. After a shutdown and booting from the microSD again the idle power consumption is back at 0,92w. So far i have not been able to find a reason for this. The only things i noticed was: (microSD) Device Start End Sectors Size Type /dev/mmcblk1p1 32768 557055 524288 256M Linux extended boot /dev/mmcblk1p2 557056 61702144 61145089 29.2G Linux filesystem (eMMC) Device Start End Sectors Size Type /dev/mmcblk0p1 32768 59998207 59965440 28.6G Linux filesystem While microSD uses a vfat partition for /boot and an EXT4 partition for the OS the eMMC has a single EXT4 partition for everything. Does that change how the system is booting? https://github.com/radxa/u-boot/commit/bf47e8171f44804c7f2004f53d3f05801f8dbbb8 Different drive strength settings in u-boot for when eMMC is boot drive or not? Can that really increase the power usage of the eMMC by 0,3w?

Is it possible to activate PCIe ASPM L1 substates with the NanoPi R6C / RK3588s Soc in general? > lspci -vvv | grep ASPM LnkCtl: ASPM L1 Enabled; RCB 64 bytes, Disabled- CommClk+ L1SubCap: PCI-PM_L1.2+ PCI-PM_L1.1+ ASPM_L1.2+ ASPM_L1.1+ L1_PM_Substates+ L1SubCtl1: PCI-PM_L1.2- PCI-PM_L1.1- ASPM_L1.2- ASPM_L1.1- My M.2 NVMe SSD supports all L1 substates but setting pcie_aspm.policy to "powersupersave" has no effect. Max is "powersave" to activate ASPM L1 and that works. Is this a limitation of the SoC or just not implemented in the armbian driver / kernel?
